feat(errors): improve Nix error message legibility

[Naxdy]

The message is a full proper nix error message anyway, so the extra text is unnecessary.

📝 Walkthrough

Walkthrough

Updated the NixError::Nix error variant's display message in the thiserror derive macro by removing the fixed prefix text "a generic Nix error occurred: " and changing the format to display only the inner string value.

Changes

Cohort / File(s)	Summary
Error message simplification nix-bindings-util/src/lib.rs	Removed fixed prefix text from NixError::Nix variant's #[error(...)] attribute; now displays only the inner String without the "a generic Nix error occurred: " prefix.

Poem

A rabbit hops through code so clean,
Trimming words from error's scene,
No fluff, no fuss, just truth so bright,
The message now feels just right! ✨

Check name	Status	Explanation	Resolution
Title check	⚠️ Warning	The title claims to 'improve Nix error message legibility', but the change actually removes descriptive context by deleting the prefix text 'a generic Nix error occurred: ', which could reduce clarity rather than improve it.	Revise the title to accurately reflect the change, such as 'refactor(errors): simplify Nix error message format' or clarify the PR description to explain why removing context improves legibility.
